Hello all,
I'm planning a Rohn 25 guyed tower, at this time likely 120ft or 130ft.
At the Rohn site, it appears wind load limit for a 120ft 25G would be 17sq ft.
I will likely put up a C31XR on top and a 2nd C31XR sidemounted at around 60ft.
This is about 20sq ft wind loading.
Is anyone using this configuration with Rohn 25 ?
Alternately I could have just the C31XR on top and add a 2 el 40m shorty yagi. This would be right around 17sqft.
I already have almost 200ft of Rohn 25, so was hoping to use that.
However, I'm thinking I may need to sell it and buy Rohn 45 or 55 to go with a pair of C31XRs and then possibly a 40m yagi as well.

I know this can be subjective with many opinions. One local ham has had a TH7 and 3 el 40m KLM up for almost 30yrs on 100ft of Rohn 25 without trouble, yet I'm sure that exceeds the recommended wind load.

Thanks and 73 to all, hope you found a vaccine shot if you wanted one,
NJ was not bad, got my 2nd shot in mid-Feb,
